Sorry, for some reason I was digging through the thread but it wasn't until I posted my question that I saw the other posts for the link to the fix. mea culpa
FWIW- it's in 1.5RC4 too- I found the Q&T thread which lead me here, just to be pointed back there (Grr) - I made the 2 string mods (one remove, one alteration) but the php file error still exists-
I'm no coder, and am hoping by the time I get enough users online into CB this will be ironed out- Anyone else have a fix for either RC3 or RC4?
